GB/T 35031 "User-Side Energy Management System" is a recommended standard to guide the standardization of user-side energy management, aiming to achieve unified standards. Technical requirements, data interface models, and evaluation systems are needed to address the long-standing challenges faced by different manufacturers and stakeholders in my country's user-side energy management field. The problem of compatibility between users and different systems. Given that user-side energy management systems involve multiple dimensions such as systems and components, hardware and software, communication protocols, data interfaces, monitoring and evaluation, etc. The content of GB/T 35031 can be clearly divided into several relatively independent but interconnected parts, so GB/T 35031 is proposed to consist of eight parts.

1.Guidelines. Provides an architecture model and general requirements for user-side energy management systems.

2.Main Station Functional Specifications. This includes the functional architecture, functional definitions, and requirements of the user-side energy management system main station software.

1.General Requirements for Subsystem Interface Gateways. Includes the functional model, functional requirements, and electrical specifications of the subsystem interface gateway. General requirements for machinery, inspection, etc.
